Implementing BM25 for Hybrid Search in AlloyDB & Cloud SQL
Google Cloud has added native BM25 support to AlloyDB and Cloud SQL, enabling high-quality, industry-standard full-text ranking directly within the database to improve RAG and hybrid search performance.
Google Cloud TechIntegrating Gemini Intelligence into AlloyDB via AI Functions
AlloyDB AI functions allow developers to execute LLM-powered tasks like ranking, summarization, and forecasting directly within SQL, using optimized local models to achieve massive performance gains and cost reductions over standard row-by-row LLM calls.
Google Cloud TechStop Adding Indexes to Fix Slow Queries — You’re Quietly Killing Your Writes
Every index you add is a permanent tax on write performance. To maintain system health, you must audit for unused and redundant indexes, as these provide zero read benefit while slowing down every insert, update, and delete.
Accelerating Hybrid Search in PostgreSQL with AlloyDB AI
AlloyDB AI integrates vector search, full-text indexing, and Gemini-powered summarization directly into PostgreSQL, enabling sub-second hybrid search across massive datasets without external pipelines.
Google Cloud TechFixing RAG Pipelines by Optimizing Chunking, Not Models
Most RAG failures are caused by poor data retrieval, not model hallucinations. Improving chunking strategy and inspecting raw retrieved data is the most effective way to improve accuracy.
Firebase SQL Connect: PostgreSQL Integration and SDK Generation
Firebase SQL Connect is a new PostgreSQL-based database service that abstracts backend complexity by auto-generating strongly typed client SDKs from GraphQL schemas, enabling real-time updates, native SQL extensions, and seamless AI/API integrations.
